Building both glibc's in a mock root (with redhat-rpm-config) installed resulted in two rpms that did not conflict with one another, so I could continue building gcc in the updated mock root. The x86_64 version compiled fine so far, going to start the i686 build in a minute. I suppose my guess that the difference in check summing in the original builds was the cause of my issue was right. At least it had something to do with the macro setup as the absence of redhat-rpm-config was the only difference in both build environments.
